How long does take for an iceberg to reach Newfoundland from Greenland?

There are too many variables involved, the size of the Berg, relative density, water temperature and ice-state- ice would inhibit motion in any case, tides and currents, its a big oceanographic problem before you can authorized ice-breakers to use their five inchers. the Russians experimented with Calcium Chloride shells fired from icebreaker"s cannons and this seemed to have an effect, like rock salt (don"t call it dry ice, that"s CO-2) in melting ice obstructions. Your question is interesting but there are too many variables, including weather oriented ones, to give a pat or statistical answer like, for example Mach"s constant which is 760 MPH at sea level.
